(DAILY CALLER) On Dennis Miller’s radio show Thursday Lord Christopher Monckton, a former policy adviser to British Prime Minister Margaret Thatcher and an activist against global warming “alarmism,” went all-in on questioning President Barack Obama’s citizenship.

Monckton, the 3rd Viscount Monckton of Brenchley, hinted about his position on the issue in April 2010 at a tea party rally on the National Mall near the White House. But on Miller’s show, he said the birth certificate issue was far more important that combatting so-called anthropogenic global warming.
